New to Deviation, project in progress, need advice

Hi all !

I need your advice cause i am totally newbie in radio technology.

I have 4 toys actually :

1x Hubsan X4 v1 ( quad heli )
1x Hubsan X4 Video ( quad heli )
1x Traxxxas E-Revo VXL ( car )
1x Esky Lama V4 ( heli )

I have a project to have an all in one radio for at least my 3 first devices. ( does'nt know if i can change the receiver in my lama, need to check )

Does i am wrong if :

- Got a Devo 7e radio

- Got a Devo receiver for my car

- Got an A7105-500m wireless transceiver Antenna
( www.ebay.com/itm/A7105-500m-wireless-tra...wandbid=300777696218 )

- Put the A7105-500m with this tutorial :
( www.hacksmods.com/2013/04/walkera-devo-7...x-flysky-hubsan-mod/ )

- Put the new receiver in my car

- Flash the Devo with Deviation firmware 3.0


That's good ?

How does the binding/pairing will act with my two different Hubsan ?

EDIT : or another question, the Devo F4 is nice, but doesn't Devolution compatible.

Do you know a hubsan radio compatible with an FPV integrated screen ?


Thanks !
